:I started reading through the code, looking for sections that were relevant to problem I was trying to solve. For example, since I was adding a new math function, I looked in the code for where the other math functions were defined. I found the code for "+", "-", "*", "/", "random", etc. in talogo.py and I found code for generating blocks in taturtle.py. It was an iterative process. I proceeded by trial and error and made lots of mistakes along the way. In the process, I learned a lot about the overall structure of the code.

:Many Activities has an Authors file. Most Activities have additional author information on their respective wiki pages, e.g., [http://wiki.laptop.org/go/Turtle_Art]. Most Activities have a maintainer in the trac system [http://dev/laptop.org/query]. TurtleArt tickets are "Owned by: bss".
